About the Dynamat Xtreme Wedge Pack

You've installed speakers and subwoofers so you can hear clear, vibrant music in your car. Why put up with road noise? Dynamat Xtreme Wedge Pack minimizes your car's irritating resonances and screens out noise from the wind, your engine, and surrounding traffic, all factors that can jeopardize sound quality.

You've installed speakers and subwoofers so you can hear clear, vibrant music in your car. Why put up with road noise? Dynamat Xtreme Wedge Pack minimizes your car's irritating resonances and screens out noise from the wind, your engine, and surrounding traffic, all factors that can jeopardize sound quality.

Dynamat designed this self-adhesive Xtreme sheet for general use on rear decks, doors, floors, and trunks. Apply this sheet to a car door before mounting a speaker, and you'll transform flimsy metal into a solid, non-resonant baffle. Unlike Dynamat Original, you can also install Dynamat Xtreme on trunk lids, roofs, quarter panels, and even under your car's hood. And Xtreme proves four times more effective than Original in reducing noise, so you'll hear your music and nothing else.

Dynamat 10425 Xtreme

It is hard to tell how much benefit in sound quality you get by applying this product since I was also installing new car door speakers.
There should be a big warning label to wear gloves. The foil edges cut you before you realize. I should have searched better and maybe bought the speaker molded cups instead. The sales person did not talk about those.

Pros: Easy to cut and apply

Cons: wear gloves to prevent cuts. No way to tell how well (or not) it is working

Dynamat Xtreme Wedge Pack

Good stuff. Gets rid of vibrations and rattles. Only gave it 4 stars because it is expensive. Also, it comes rolled up, which makes peaks and valleys, think topographical map. You can see the peaks and valleys in the picture. Seems if it came shipped flat, not rolled, from the factory it would be flat and be easier to roll out once stuck to the panel. Just an observation though not a deal breaker. Adhesive is strong and sticks very well in spite of this.

Not great for use as a gasket

I've always used Dynamat "Original" when installing front door and/or rear deck speakers. I like to use it as a gasket and have always been very happy with the outcome. I had an old roll from many years ago that I have been using on multiple cars. It finally ran out and I could not find "Original" for sale. Discontinued? Anyways, bought this and it is alright. It's more like thick foil with gum stuck to it. Works as intended but not as good as the "Original" for making gaskets.

Pros: Stops rattles

Cons: Like thick foil with gum stuck to it. Lots of creases and hard to get a good smooth look.

Great product

I cut this up into strips that was really easy to adhere to the metal areas behind and around the speaker. When I turned my stereo back on after installing the Dynamat, there was a really big improvement to the sound quality of my system. I would recommend this product to anybody who is serious about having a nice, clean sounding system for your car. No more silly rattle.

Good add-on

I was on the fence with adding this onto my order and in the end I'm glad that I did. It made for an easier and better installation and it was worth the cost. I wrapped a layer in front of and behind each of four door speaker openings when replacing stock door speakers. I then attached the Crutchfield supplied speaker adaptors over the Dynamat - no rattle. I had enough left over to attach decent size squares to the doors' shells behind each speaker figuring it can't hurt and may absorb some vibration.

It helps

It helps, I guess. The doors shut with more of a thud now. I installed it with when I installed new speakers so I have no point of reference to compare its effect on the sound but I know it didn't hurt.

Does what it's supposed to.

It's Dynamat. It damps panel vibration. It's not a fix for poor system design, cheap speakers, etc. Does exactly what it's supposed to do. Would be nice if it was a little cheaper, but you get what you pay for.

Does what its supposed to do

I like the product, its easy to work with and provides a true benefit not only noise attenuation but also for sealing screw holes in the door that hold the speaker in case/when water gets in there. I used this as a "gasket" for installing my speakers in the door and folded the pie sliced pieces from the speaker opening up and to the inner side of the door as well.

Overpriced

I will not argue against what this product does. Rather, I'd like to point out what it is: It is foil backed, butyl rubber. Other manufacturers produce foil backed butyl rubber at a fraction of the cost of Dynamat. The only difference I have detected is that Dynamat's foil layer *might* be a little heavier. There is nothing magical about Dynamat's foil backed butyl rubber. It is what it is, same as any other foil backed butyl rubber. Do yourself a favor and a little research into the material used, and save yourself a few $$$. Avoid foil backed asphalt and go with butyl. Butyl has better adhesion than aspalt and won't small like asphalt when your car has baked in the sun all day.

Pros: Does what it says

Cons: The premium paid for the name brand is out of line with the product itself.

Good Stuff

I replaced the speakers in my Dodge Ram 1500 and used this product as
part of the install. Simple installation. Product is a "mushy" type of rubber
that cuts easily and adheres well to clean surfaces. I liked how the
speakers settled into the rubber when I screwed them in. I have no
buzzing or vibration issues with this installed. I figured it was worth a few
extra dollars to reduce or eliminate the possibility of unwanted vibrations
or rattling. Also, no rubber smell from this product at all.

Customer Q&A

Q

Crutchfield asked: Why did you buy this?

this product is just awesome, deadens everything.
[ David Jun 12, 2019 ]

A

Prevent Vibration and improves sound quality
[ FRANK R Dec 18, 2018 ]

A

Needed enough sound deadening for 4 speaker openings, and one pack of this was a better deal than 2x packs of the 10" x 10" sheets
[ EVAN J Nov 13, 2018 ]

A

better sound
[ Bryan May 03, 2018 ]

A

I hope to install this material on the metal frame behind the kick panels of my 1968 Cougar. I am installing 6 1/2" speakers in custom aftermarket kick panels to put speakers where they never were intended.
[ John Apr 24, 2018 ]

A

I have a Rockford Fosgate Punch sound system in my Toyota truck that sounds awesome, however there are a bit of plastic components inside the truck that rattles a bunch and ruins the sound quality a quite a bit. I'm hoping that the Dynamat will help drastically reduce or even better, eliminate, the rattling.
[ Anthony Mar 21, 2018 ]

I have some resonances coming from my driver side door and I'd like to try using this product to get rid of them.
[ James Mar 16, 2018 ]

A

Because I hate listening to rattling after hooking up a nice system
[ Joseph fuller Jan 06, 2018 ]

A

this was over a year ago for my car speaker
[ Hal Jun 21, 2017 ]

A

Adding a lot more power to my door speakers so I will need to deaden the door cards heavily to prevent rattling.
[ John Jun 18, 2017 ]

A

I read the reviews. Even though this product is a more money than the other products out there, it seems to be thicker and people claim that it does what was designed to do. I will let you know once I install it.
[ Timothy Jun 09, 2017 ]

A

Kevin steered me to this instead of 2 10x10 door sets. This set has more material and is actually cheaper than 2 of the 10x10 sets. Saved me over $10. Thanks Kevin!
[ Scott Jun 02, 2017 ]

This product provides enough Dynamat product to cut into squares to apply to my trunk lid and other areas. Great idea when adding a sub-woofer to stop rattle from trunk lid and more.
[ Barrett Hall Feb 18, 2016 ]

A

Dynamat has a good reputation and the piece will be big enough
[ Steve Feb 08, 2016 ]

A

Reduces the vibrations. I wasn't sure how well this would work but I have no doubts anymore.
[ Paul Dec 18, 2015 ]

No tape needed. I use a heat gun on the lowest setting and it did the job

[ FERNANDO C Jan 03, 2014 ]

A

The material is self adhesive and can be easily cut and fitted. A hand roller is recommended to make good adhesive contact eliminating air bubble entrapment. A strong pair of upholstery shears or scissors works well for cutting and trimming if required. Do most of your cuts and fitting before you remove the protective adhesive backing for the final application, repositioning is next to impossible without damage once it has been installed. After you make cuts foil backing will have extra sharp edges in those areas and gloves should be considered to prevent injury. Finishing tape is not required but can be used on seams or overlaps if desired. It is a great product that conforms to odd shapes and works as it is designed too.
